windows api 动态修改菜单项语言

上次的windows程序设计要求这么做了。搞了好久才搞定。

void setLanguage(HINSTANCE hInstance,  HMENU hMenu,int langue)//简单的写了一个函数，传递实例句柄、菜单句柄（整个菜单句柄）、语言编号，对资源文件中的字符串资源id相对应，比如中文id是cnid，英文是cnid+1,日文是cnid+2，对应的langue值就是0/1/2
{
	int nMenuItemCnt=GetMenuItemCount(hMenu);//获取菜单项数量
    WCHAR szBuffer[30];

	int startMenuStringId=FileCN,startMenuID=EXIT;
    for (int i = 0; i < nMenuItemCnt; i++) 
    { 
      HMENU subMenu= GetSubMenu(hMenu,i);
	  int subMenuSize=GetMenuItemCount(subMenu);
	  LoadString(hInstance,startMenuStringId+langue,szBuffer,30);//根据语言读取字符串资源
	  ModifyMenu(hMenu,i,MF_BYPOSITION,i,szBuffer);//修改菜单
	   startMenuStringId+=2;
	  for(int j=0;j<subMenuSize;j++)//修改子菜单
	  {
		 
		   LoadString(hInstance,startMenuStringId+langue,szBuffer,30);
		    startMenuStringId+=2;
		  ModifyMenu(subMenu,startMenuID,MF_BYCOMMAND,startMenuID,szBuffer);
		  startMenuID++;
	  }

    } 
}
